Main Material

The development of fishing and marine tourism requires the support of naval architecture, especially in small boat. The use of wood as the main material for shipbuilding has recently become a problem considering the decreasing availability of wood, while the use of fiber is classified as less environmentally friendly because it uses chemical resin and difficult to repair when it breaks and cannot be recycled. The aim of this research is to design the High-Density Polyethylene (HDPE) boat. The design was carried out by using naval architect design software. The stability of boat was calculated by using three loading conditions such as when leaving the port, in the sea and when returning to the port. The International Maritime Organization (IMO) safety criteria was using to evaluation of boat stability where the three loading conditions have met the IMO standard. The construction of HDPE boat was carried out by using DNV rules.

Aiming to systematically convert post-consumer plastics in building materials, we compounded recycled high-density polyethylene and sugarcane bagasse. We ranged the polymer/filler ratio from 100/0 to 60/40, and assessed the properties using optical microscopy, water absorption test, adhesion by tape test, low-field nuclear magnetic resonance, dynamic-mechanical analysis, and wide-angle X-ray diffractometry. The optical microscopy of the triturated bagasse showed the reduced and heterogeneous fiber sizes. The absorption and adhesion test showed that the polymer more heavily filled with bagasse can better absorb and anchor paint with organic solvent base. The dynamic-mechanical analysis and wide-angle X-ray diffractometry led us to believe that the bagasse fibers somehow structured the amorphous region amongst the crystallized lamellae of the polymeric matrix. We concluded that these composites have interesting properties to produce building materials.

Salah satu cara yang digunakan di Indonesia dalam menanggulangi berlimpahnya jumlah sampah plastik di lingkungan perairan adalah dengan menggantikan kantong plastik berbahan polimer polietilen (PE) dengan plastik oxodegradable yang disebut oxium. Penelitian ini dilakukan dengan tujuan untuk melihat pengaruh mikroplastik polietilen jenis HDPE (High Density Polyethylene) dengan plastic oxodegradable oxium. Penelitian dilakukan dengan menggunakan mikroalga Tetraselmis chuii sebagai mikroorganisme yang akan mendapat perlakuan mikroplastik dengan konsentrasi yang berbeda. Dari Hasil pengukuran optical density untuk menentukan laju pertumbuhan mikroalga Tetraselmis Chuii menunjukkan bahwa laju pertumbuhan Tetraselmis  dengan perlakuan mikroplastik polietilen mengalami penurunan yang signifikan dibandingkan dengan mikroplastik oxium. Konsentrasi mikroplastik ikut berperan dalam menentukan laju pertumbuhan Tetraselmis chuii di mana pada perlakuan mikroplastik oxium terjadi penurunan hingga 37,66% pada konsentrasi mikroplastik 300mg/500mL dan 81,70% pada perlakuan mikroplastik polietilen dengan konsentrasi 200mg/500mL. Mikroplastik polietilen dan oxium memberikan dampak negatif pada organisme tingkat rendah disebabkan oleh kemampuannya dalam melepas bahan aditif yang bersifat toksik sehingga diperlukan solusi yang lebih baik untuk menggantikan fungsi plastik dengan bahan yang lebih ramah bagi lingkungan hidup.  ABSTRACTOne of the methods used in Indonesia in tackling the abundance of plastic waste in the aquatic environment is to replace plastic bags made of polyethylene (PE) polymer with oxodegradable plastic called oxium. This research was conducted with the aim of examining the effect of HDPE (High Density Polyethylene) microplastic polyethylene with oxodegradable oxium plastic. The research was conducted using the microalgae Tetraselmis chuii as microorganisms that will receive microplastic treatment with different concentrations. From the results of optical density measurements to determine the growth rate of Tetraselmis chuii microalgae, it was shown that the growth rate of Tetraselmis with polyethylene microplastics treatment decreased significantly compared to oxium microplastics. The concentration of microplastics played a role in determining the growth rate of Tetraselmis chuii where in the oxium microplastic treatment there was a decrease of up to 37.66% at the microplastic concentration of 300mg/500mL and 81.70% at the polyethylene microplastic treatment with a concentration of 200mg/500mL. Polyethylene and oxyum microplastics have a negative impact on low-level organisms due to their ability to release toxic additives so that better solutions are needed to replace the function of plastics with materials that are more environmentally friendly.

Blending Method

Enormous amounts of plastic wastes are generated worldwide and the approaches related to plastic recycling or reusing have become the research focus in the field of composite materials. In this study, green composites were prepared via melt-blending method using high-density polyethylene (HDPE) sourced from plastic bags as a matrix and sugarcane bagasse (SCB) fiber as reinforcing filler. The effects of fiber loading (5, 10 and 15 wt%) and fiber modification on the mechanical and dimensional stability (weight gain by water absorption) properties of the green composites were investigated. Results showed that the inclusion of SCB fiber into recycled HDPE matrix increased the composite stiffness but decreased the mechanical strength and resistance to water absorption. With the fiber modification through alkali treatment, the mechanical strength was remarkably improved, and the modulus and water absorption of the composites were found to be reduced. From the finding, it can be concluded that the prepared green composites free of coupling agent could add value to the plastic and agricultural wastes, and serve a potential candidate to replace some conventional petroleum-based composites.
